Weight adjustable bat

ABSTRACT

A bat made of metal material includes an opening defined in a distal end of the barrel and an inner threaded portion is defined in the opening so as to receive a cap which is threadedly connected to the inner threaded portion and includes a weight such that the users can replace different caps to adjust the weight center of the bat as needed. The cap can be easily replaced by using a securing tool which includes insertion portions to be engaged with axial recesses in the cap.

FIELD OF THE INVENTION

The present invention relates to a bat, and more particularly, to a weight adjustable bat.

BACKGROUND OF THE INVENTION

Baseball is a popular exercise and the players need a suitable bat to have better performance.

A conventional bat has a fixed weight and weight center because no movable or adjustable part is added to the bat. However, players of different heights need different bats whose weight enters are different so that professional players have custom-made bats. Nevertheless, for most of the players, it cost a lot to own custom-made bats and too many bats will be a burden for the team.

The present invention intends to provide a weight adjustable bat which includes a cap removably connected to the bat and the cap has a pre-set weight so as to achieve the purpose of a weight adjustable bat.

SUMMARY OF THE INVENTION

The present invention relates to a bat made of metal material and the bat is a hollow cylindrical body including a handle and a barrel. The handle has an exterior diameter smaller than an exterior diameter of the barrel. An opening defined in a distal end of the barrel and includes an inner threaded portion so as to be threadedly connected to a cap. A washer is located between the barrel and the cap to seal the opening.

The primary object of the present invention is to provide a bat that includes a cap which can be replaced and the cap has different weight so as to adjust the weight center of the bat.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 3, the bat 1 of the present invention is made of metal material such as Aluminum Alloy and comprises a hollow cylindrical body 10 and a cap 20. The bat 1 includes a handle 11 and a barrel 12. The handle 11 has an exterior diameter smaller than an exterior diameter of the barrel 12 so that a gradually divergent section is connected between the barrel 12 and the handle 11. A grip material 13 is mounted to the handle 11 for providing a better grasp of the bat 1. An opening 15 is defined in a distal end of the barrel 12 and includes an inner threaded portion 16 which extends axially toward the handle 11.

The cap 20 has an exterior diameter larger than an interior diameter of the opening 15 and not larger than a maximum exterior diameter of the barrel 12, such that the bat 1 has a smooth and fixed profile. The cap 20 includes an outer threaded section 22 which extends axially from an end of the at least one cap 20, the outer threaded section 22 is threadedly connected with the inner threaded portion 16. A washer 26 is located between the barrel 12 and the cap 20 so as to seal the opening 15 to prevent dust or water from entering the bat 1.

The cap 20 includes multiple axial recesses 21 defined in an end surface thereof. The axial recesses 21 are located in pairs and in radial directions around a center of the cap 20 at equal distance. The cap 20 further has an index 23 marked thereon so as to display weight of the cap 20. The index 23 can be made by any known method such as stick, printing, carving or laser carving. The index 23 can also be made integrally with the cap 20. As shown in FIGS. 4 and 5, each cap 20 includes a weight 24 received therein and the weight 24 provides the cap 20 a pre-set weight. A notch 25 can be defined in the weight 24 to obtain different weights. The caps 20 with different weights have the same size so that when the cap 20 is connected to the bat 1, the length or appearance of the bat 1 does not change.

The cap 20 is connected to the bat 1 by using a securing tool 30 as shown in FIG. 2, wherein the securing tool 20 includes a driving portion 31 and two insertion portions 32. The driving portion 31 is for users to hold and the two insertion portions 32 are inserted into the axial recesses 21 of the cap 20. The distance between the two insertion portions 32 equals to a distance between each pair of the axial recesses 21. The insertion portions 32 are perpendicular to the driving portion 31 and the securing tool 30 is substantially an F-shaped tool. The user can easily rotate the cap 20 by inserting the insertion portions 32 into the axial recesses 21 and rotating the securing tool 30.

FIGS. 6 and 7 show another embodiment of the securing tool 40 and the axial recesses 21, wherein the securing tool 40 includes a driving portion 41 and an insertion portion 42. The driving portion 41 is for users to hold and the insertion portion 42 is inserted into one of the axial recesses 21 of the cap 20. Each axial recess 21 is a polygonal recess and the insertion portion 42 is a polygonal rod. The insertion portion 42 is perpendicular to the driving portion 41 and the securing tool 40 is substantially an L-shaped tool.

The weight of center can be changed easily by replacing a cap 20. The bat 1 can be cooperated with multiple caps 20 so as to obtain desired bat 1 for different players.
